My Whirlpool gas oven will not ignite, but the stove top works.
Report This
I have a Whirlpool Model #SF368LEPS3 Whirlpool Free standing - gas range and the oven/broiler will not ignite. So far we have checked for loose connections/wires, and taken the plate off the bottom of the oven to look for a spark from the igniter. There is no spark from the igniter. My father is very handy in general, but has not worked with alot of gas ovens. I cannot afford a repairman OR a new stove, so I am hoping I can find a guide or some help in fixing it. My gut, and my online research, says that the igniter is bad and needs to be replaced, but could it be something else? What is the degree of difficulty in replacing it? If i NEED to call a repairman I will, but if there is any way I can get by without it, I would rather do that. I can supply any additional info you need, but this is WAY outside my scope of knowledge. I do not even know what search terms to use to find anything useful online. :(

Also I should mention we ran the diagnostic code finder and it said "Good" so there is no error code showing.

Thank you for your question and I understand your concern.
The tip of the electrode for the bake burner must be close enough to ground in order for it to jump spark. There must also be a good ground or it will jump spark to the bake burner. Make sure the bake burner is making a good connection to the oven frame.
There is also several other components in the oven circuit too that must be operational before the bake spark igniter will spark. The Oven control/clock assembly must close the bake relay and complete the 120 volt power source to the spark module. When the oven is set to bake, the bake relay must close and provide 120 volts to the RED wire connected to the spark module. The voltage supply must be measured across the Red wire and the White wire after programming a bake cycle. If voltage is not present, the electronic oven control is likely faulty. If 120 volts is measured across the red and white wire, it could have a faulty spark module. The spark igniter is not likely faulty unless the ceramic insulator is cracked. So, in order for the spark igniter to begin sparking, there must be a good ground, the oven control must close the bake relay and there must be voltage supplied to the spark module. I added an image below of the wiring diagram along with the bake strip circuit.
NOTE: I do not recommend making voltage measurements unless you have experience and feel safe and confident in doing so; otherwise I suggest calling a service technician to diagnose and repair your range.
If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
